WiiM Pro Audio Streamer Bit-Perfect DAC AK4493SEQ WiFi AirPlay 2 DLNA Chromecast Multiroom Bluetooth 5.1 24bit 192kHz The WiiM Pro is a compact, extremely versatile and high-performance audiophile streamer that transforms a conventional audio system into a connected system. It opens the door to music streaming via WiFi and Bluetooth 5.1, and is compatible with numerous transmission modes such as DLNA/UPnP, AirPlay 2, Google Chromecast, Alexa Music Cast, Spotify Connect and Tidal Connect. Several units can also be used in combination to set up a true multi-room system, with full remote control via the WiiM App mobile application or a voice assistant such as Alexa, Google Assistant or Siri. The WiiM Pro is an improved version of the WiiM Pro, incorporating a better DAC and ADC as well as more efficient OPAs. Its performance, particularly with regard to its line input and output, has been revised upwards, with improved SNR and THD N for even more accurate and transparent sound reproduction. The main improvements to the WiiM Pro are : A better ADC for line input: WiiM Pro uses a TI Burr-Brown PCM1861 ADC, supporting 32bit 192kHz PCM streams at output, with an SNR of 110dB. Ultra-low-noise clock, power supply and circuitry: The WiiM Pro features an ultra-low-noise clock and power supply and a PCB design optimised to achieve a THD N of less than -110dB for the analogue output. AKM DAC and TI OPAs for improved line output quality: A new-generation AKM AK4493SEQ DAC is now used to achieve a very low level of distortion and a wide dynamic range thanks to AKM Velvet Sound technology. This chip supports PCM streams up to 768kHz and DSD up to DSD512 while achieving an SNR of 120dB (A-wt) and a THD N of -110dB. Remote control: A voice remote control is now included, allowing you to control the WiiM Pro from the comfort of your sofa, without having to take out your phone.
